The pre-cooling method is one of the methods that can be done to prevent these quality changes, the goal is to extend the shelf life of pakcoy. The quality of pakcoy is influenced by environmental conditions during storage. Suitable packaging can prevent the rate of respiration. Respiration can cause a deterioration in the quality of the pakcoy, so before storage it needs to be packaged. This study aims to determine the duration of pakcoy storage packaged with LDPE plastic clips based on changes in weight, moisture content, color, and texture during cold storage in 2 (two) pre-cooling methods, namely room cooling and hydro cooling and comparing the quality of pakcoy carried out pre-cooling with room cooling and hydro cooling methods. This study used experimental methods with pre-cooling treatment, namely room cooling and hydro cooling, data collection was carried out as many as 3 samples per treatment. The data is presented in tables and graphs and then analyzed descriptively.

The purpose of this study was to design and technically test a household-scale coconut husk stove with a gasification system. The research method was carried out by design and experimental testing, then the resulting data were analyzed descriptively. In this study, two types of stoves were designed and manufactured which were practical for application on a household scale using a gasification system made from coconut coir. The first stove that uses an air blower can reach a temperature of 740 ℃ and is tested with 1.5 liters of water, so the water can boil for 9 minutes. The second stove, which does not use an air blower, can boil 1.5 liters of water for 11 minutes at a temperature of 608℃. Both stoves have a waiting time to produce gas that is not much different, which is about 3 minutes with an initial fuel mass of 300 g. The results of economic calculations show that the cost of making this stove is relatively cheap and easy to maintain.

North Sulawesi as one of the highest coconut-producing regions in Indonesia is still trying to increase the value of existing coconut products. One of the problems faced in increasing the value of coconuts is the decreasing number of workers who climb and peel coconuts. Coconut coir as a very significant part of the amount in one fruit still needs attention so that its value can be increased. Coconut coir has the potential to be utilized but requires processing equipment, which can decompose coconut coir into fiber (coco fiber) and dust (cocopeat). The problem is that decomposers are relatively difficult to obtain in this area, and if they are available, they have to be imported from other islands and they are expensive. For this reason, this research was made, namely to make and test the performance of coconut coir processing equipment. The research method was carried out experimentally, and the data obtained were analyzed descriptively. Experiments were carried out using the engine rotation speed: 500 rpm, 600 rpm, and 700 rpm. The raw material for coconut fiber used was 10 kg with three repetitions. From the results of the study, it was found that the best results were at a speed of 500 rpm which was able to produce the highest yield of 90.9 percent of total cocopeat and coco fiber, while at speeds above 500 rpm, namely 600 rpm and 700 rpm, the higher the coir material that became granules dust. The highest decomposition yield of coir into coco fiber was at 500 rpm, namely 95.68 kg/hour or as much as 765.44 kg/day (note: 1 day = 8 hours).

 Manure is a fertilizer that comes from a mixture of livestock manure, urine, and leftover animal feed. The purpose of the study was to see how the growth of lettuce plants that were given pig manure were incubated. This study used a completely randomized design (CRD) with 9 treatments, namely T0 (control), T2 (0 weeks incubation without soaking), T1 (1 week incubation without soaking), T3 (2 weeks incubation without soaking), T4 (3 weeks incubation without soaking). without soaking), T5 (0 weeks of immersion incubation), T6 (1 week of soaking incubation), T7 (2 weeks of soaking incubation), T8 (3 weeks of soaking incubation), each treatment was repeated 3 times to obtain 27 experimental plants. Parameters observed were plant height, number of leaves, fresh weight, and root volume.
 Based on the results of the study it can be concluded that the application of organic fertilizer from pig manure which was incubated with immersion and without immersion had no significant difference to plant height, number of leaves, and root volume but significantly different to fresh weight of lettuce plants.

 Abstrak
 Pengembangan kawasan Pantai Timur Minahasa menjadi kawasan pariwisata, menyebabkan kecenderungan terjadi perubahan pemanfaatan lahan. Kecamatan Kombi adalah salah satu wilayah di Pantai Timur Minahasa yang mengalami perubahan penggunaan lahan dengan banyaknya investor yang membangun kawasan pariwisata di sana. Lajunya pembukaan-pembukaan lahan di daerah tersebut, dapat mempercepat proses terjadinya erosi. Penelitian ini dilaksanakan dengan tujuan mengetahui tingkat bahaya erosi tanah di Pantai Timur Minahasa khususnya di Kecamatan Kombi agar dapat mencegah kerusakan tanah sehingga kelestarian lingkungan dapat terjaga dan pengembangan kawasan pariwisata di daerah tersebut dapat berlanjut. Metode yang digunakan dalam penelitian ini adalah metode overlay untuk pembuatan peta digital dan perhitungan erosi menggunakan metode USLE. Hasil analisis menunjukkan kawasan Pantai Timur Minahasa khususnya di Kecamatan Kombi memiliki tingkat bahaya erosi ringan seluas 1492.10 Ha, tingkat bahaya erosi sedang seluas 5036.35 Ha, dan tingkat bahaya erosi berat seluas 6970.94 Ha.
