Sebagian masyarakat Maluku yang tinggal di pedesaan masih menggunakan tungku dengan bahan bakar kayu untuk memasak. Desa Laha yang menjadi khalayak sasaran, sebagian masyarakatnya untuk memenuhi kebutuhan dapur menggunakan energi alternatif dari kayu bakar, yang diperoleh dari pohon (hutan) di sekitar lingkungan. Tidak hematnya penggunaan kayu, dikarenakan mereka menggunakan tungku sistem terbuka. Untuk itu teknologi yang ditawarkan adalah menggunakan kompor biomassa berdinding isolasi dengan sistem tertutup, dimana proses pembakaran kayu dilangsungkan di dalam ruang yang bebas dari pengaruh hembusan udara lingkungan. Metode yang digunakan dalam kegiatan ini adalah metode penyuluhan dan pelatihan bagi masyarakat mitra. Hasil dari kegiatan ini adalah masyarakat bisa menggunakan kompor biomassa berdinding isolasi untuk menghemat pemakaian bahan bakar kayu sehingga dapat menjaga kelestarian hutan.

The oil contained in clove leaves can be taken through the distillation process. The distillation process is carried out to separate the clove oil from the water contained in the leaves. The kettle operated is 2.5 meters high and 2 meters in diameter. The inner side of the kettle is divided into 2 rooms, at the bottom with a height of 1 meter filled with water and at the top with a height of 1.5 meters filled with clove leaves. The loading capacity of clove leaves is 1 ton and the water required is 2.5 m3. With the length of time the clove oil refining process lasts for 8 hours. Without changing the equipment specifications, efforts can be made to shorten the production time, by increasing the enhancer temperature above 26 oC. Data sourced from the distillation equipment specifications are needed to analyze the amount of energy required during the distillation process, as well as the determination of the distillation time. The analysis was carried out with 3 stages of variation of the initial water enhancer temperature of 26 oC, 50 oC and 75 oC. The temperature of the replacement water entered into the kettle is 26 oC, resulting in a distillation time of clove oil for 8 hours. When the replacement water temperature was increased by 50 oC, the distillation time was 7.89 hours. The more the enhancing water temperature is increased by 75 oC, the distillation time decreases to 7.786 hours. Thus, the distillation process time of clove oil can be shortened by increasing the initial temperature degree of the replacement water.

Kenari (Canarium indicum L) belongs to the Burseraceae family and is one of the endemic fruits in Indonesia, especially Maluku. Walnuts have a tough shell that encloses the flesh, to get the flesh without damaging it careful effort is needed. This study investigated the strength of walnut shells through mechanical testing to determine the amount of impact force needed to break the walnut shell. The mechanical test carried out is a compression test and impact test. The values of these tests assist in determining, measuring, and analyzing the minimum and maximum force loads required to crack a walnut shell. Tests were carried out on walnut shells from 6 different villages on Ambon Island and Saparua Island. The impact test where the highest impact absorption energy value was found in walnut shells from Booi Village, namely 23.18 J/mm2, and the lowest in walnut shells from Morela Village, 22.40 J/mm2. In the compression test where the lowest value was found in walnut shells from Morela village with a value of 3.61 MPa while the highest value was found in walnut shells from Booi village, namely 5.24 MPa. Whereas the minimum compressive force is 16.22 kgf/mm2 and the maximum compressive force is 17.61 kgf/mm2.

The oil pipeline network is a critical infrastructure that plays a vital role in the oil and gas industry. However, one of the significant challenges faced by this pipeline system is corrosion. Corrosion is a chemical process that leads to the deterioration of metal quality due to electrochemical reactions with the environment. Corrosion in oil pipelines not only reduces the wall thickness but can also result in leaks, structural damage, and even accidents that negatively impact human safety and the environment.The objective of this research is to analyze the corrosion rate in the elbow joints of oil pipelines at PT PLN (Persero) ULPTD Poka. This study employs a quantitative method involving two variables. The independent variable is the elbow type, specifically the 90Â° elbow, while the dependent variables are the corrosion rate calculations and the remaining service life (RSL) of the elbow pipes.The results indicate that the corrosion rate varies at each measurement point on the elbow joints. The RSL calculations show significant variation based on the thickness of the pipe wall at each elbow. The highest RSL values were found in elbows 3, 4, 5, and 8, with a remaining service life of up to 49.5 years. Conversely, elbow 1 had the lowest RSL at 38 years. The higher RSL in some elbows suggests that despite experiencing corrosion, the remaining thickness is still sufficient to support the pipeline's function for a longer duration. Recommendations include the need for intensive maintenance on the oil pipeline elbow joints, especially on segments above ground and near corrosive sources.
